动脉对称狭窄部位频谱基于的流态

The flow state of spectrum of symmetrical narrow parts in artery

目的在于构建起动脉对称狭窄部位的血液流态和红细胞群的分布状态理论,这个理论是揭示该部位超声多普勒血流频谱形成机制和丰富内涵的依据。方法采用实地观察沟渠相似部位的流态,并利用相关数理理论进行科学论证。结果构建起动脉对称狭窄部位血液流态的理论模型,红细胞群所包含红细胞数量随其流速的分布规律。结论不仅为阐明动脉对称狭窄部位血流频谱成因和内涵提供了理论依据,也为阐明动脉其他部位的流态提供了借鉴。

Objective To construct the theory of the fluid state of the blood flow of symmetrical narrow parts of artery and the distribution of the red blood cell mass. This theory is the basis of revealing the formation mechanism and the abundant connotation of the spectrum of doppler ultrasound signals from blood flow. Methods The methods used in the research include the observation of the fluid state of similar ditches, and scientific verification with mathematical theory. Results The consequence of the research includes the establishment of the theoretical model which explains the fluid state of the blood flow of the symmetrical narrow parts of artery, and the summary of the distribution rules of the numbers of the red blood cell in the red blood cell mass according to its flow velocity. Conclusion The research results indicate that in this essay, not only the theoretical basis for the explanation of the formation mechanism and the connotation of the spectrum of doppler ultrasound signals from blood flow, but also the references for the explanation of the fluid state of other parts of the artery are provided.
